This association is formed of clonal stands of about 1 m tall Prunus tenella, with an array of drought-adapted ruderal herb species. It is typical of the forest-steppe areas of east-central and eastern Europe, where it occurs in transitional zones between forest and open steppe or in terrain depressions with mesic soils in landscapes dominated by dry steppe. In the Czech Republic only three small stands occur in southern Moravia, all spatially close to steppe grasslands on loess but at the same time adjacent to man-made habitats such as arable land, vineyards, terraced slopes or dirt roads.
